This is the Think & Tinker precision DeWalt 611 Precision Grade Collet Kit containing the collet nut, 1/4 & 1/8 collets, collet wrench, all instructions and cleaning items. I paid over $100, will sell for $55 including shipping. I've upgraded to a spindle on my CNC and no longer need this kit. This kit performed well for me. Excellent condition.
